In 1980, there was a total of 300 enumerators conducting the census, which ran from April 14th to May 12th. The census questionnaire for that year addressed 9 sections: area in which a person lived, characteristics of the person, migration, education, economic activity, fertility, housing characteristics and languages spoken. Media advertisements urged cooperation from the citizens and stressed the confidentiality of personal data. It also sought to encourage citizens’ participation by advising them that the information would be used by the government and businesses to develop projects that would benefit the people.
